FrontlineSMS can help you estimate the cost of sending out messages to your groups before you send them. This can be useful if you are running on a budget, or using a pre-pay SIM card in the phone and want to verify that you have enough credit before you begin.

To estimate the cost of sending messages with FrontlineSMS and decide whether to proceed or not, follow these steps:
1. In FrontlineSMS at the bottom right of the screen, in the /SMS field, use the Cost Estimator to enter what you pay on your mobile plan per message.
2. Begin typing a new message to send.

FrontlineSMS will tell you how much credit you need to send your message to all active members of the group. Note: This estimation is just a guide. Be aware that costs may vary between networks or with international numbers.
